What is the best material to use as a cushion between the tank and stand. I was thinking of styrofoam. If so what thickness is best. This will be for a 40 gal tank.
I have been using 1/2" closed cell foam on the small to medium sized tanks. The kind of foam that hikers use to sleep on, as it will not absorb water. It also works great for under the base of pumps to calm the vibration. Just my experience.
